BOTTLE-STOPPER.

SPECIFICATION Vforming part of Letters Patent No. 704,820, dated July 15, 1902.

.Application filed January 29,1902. Serial No. 91,753. (No model.)

To @ZZ whom, t nung/conocida Be it known that I, ALEXANDER EKLUND, a citizen of the United States, residing at Attleboro, in the county of Bristol and State of Massachusetts,have invented certain new and useful Improvements in Bottle-Stoppers gl and I do hereby declare the following to be a full, clear, and exact description of theinvention, such as will enable Aothers skilled in the art to which it appertains to make and use the same.v

The present invention relates to Stoppers for bottles, and is intended for use with bottles in which granulated or powdered substances-sucm'for example, as tooth and toilet powdersare sold.

The object of theinvention is to provide a bottle-closing and"powder-d'eliveriugI stopper of such construction that the bottle will be securely closed against the escape of the contents when the stopper is in closed position and which when the stopper is moved to its open position will deliver a fixed amount of powder 4from the bulk in the bottle, suitable means being provided to normally maintain the stopper in its closed position, while actuating devices to open the stopper and means to insure thel discharge of the powderdeliv-` ered by the stopper are. also provided. Y

In the drawings whichaccompanyand form a part of this specification-is illustrated one embodiment of the invention, and in said drawingsv n y.

Figure 1 isa side elevation ,ofa bottle .with the stopper applied thereto. Fig. 2 is a eentral vertical sectional viewpf the stopper shown in Fig. 1. perspective of thestopper actuating lever. Fig.4 is avertical central sectional view taken at right angles to Fig. 2, showing the stopper in closed position in dotted lines and in open position in full lines to illustrate the action of the same in deliveringthepowder.

Referring to the said drawings by numerals, like numerals indicating like parts in the several views, lindicatesthe body-tube of the stopper, the lower end of said tube being sheathed ina cork thimble or gasket 2 to insure the proper frictional engagement of the stopper with the bottle, said stopper-tube 1 having a removable body-flange 3, mounted thereon and extending therefrom approximately midway its length,said flan ge 3 seating Fig. 3 is a, detail view in upon the top of the bottle when the stopper is in place. The said flange 3 is preferably provided with a lip 3, which enters a groove 3b in the side of the tube 1, a screw 3c locking the iiange -in position. Upon the upper end of said stopper-tube 1 is mounted a cylindrical tube-section. or sleeve 4, which has a sliding movement on the upwardly-extending portion of the stopper-'tube l, being normally maintained' in its lowermost position seated uponvthe iiange 3 of the stopper by means of a spring 5, which is housed between the sleeve 4 and the stopper-tube 1,said spring 5 bearing at its lower end upon aring 6, provided with.l projecting eyes 7, to which referencewillbe made hereinafter, vwhich is 'secured to the said sleeve 4 at or near its lower end and lies between said sleeve and the stopper-tube 1, while at its upper end the said spring 5 bears against an outwardly-stepped portion or oiset 7 formed on the stopper-tube 1. Carried by said sliding sleeve 4 and rising vertically therefrom is an arch or yoke 8 of a substantially inverted-U shape, the limbs of said yoke 8 being secured at their lower ends in the eyes 7 of the said ring- 6, which is fastened to the lower end of the sleeve 4. Depending from the center'of saidyoke 8 and preferably secured thereto by a pivotal connection 10 is a stopper-closing cap 11, said cap Vllbeing preferably a concave-convex form in cross-section for a purpose which will presently appear. The said stopper-cap 11 when the tube-section or sleeve 4 and its yoke 8 'are in their normal position rests upon an outwardly-projecting concavo-convex flange 13,

formed at the upper end of the stopper-tube 1 and preferably of equal diameter with the cap 11, the cap 11 in this position held to its seat by the spring 5, effectually closing the bottle against the egress of powder, the pivotal connection 10 of the said ycap 11 with its supporting-yoke 8 insuring-accurate seating of the same upon the iiange 12 bycompensating for any slight inaccuracies linthe vertical-movements of the sleeve 4 and its yoke 8 relative to the stopper-tube 1. In order to give an air-tight joint and prevent deterioration of the contents of the bottle, I preferably provide the stopper-cap 11 with a ring of rubber or other suitable compressible material 9 on its under side, which ring 9 seats upon theV edge of the flange 12, as clearly shown in the drawings.

Pivoted upon the ange 3 of the stoppertube 1 is a lever 13, having an overhanging downwardly-turned end which forms a thumbpiece 14, by means of which the said lever 13 may be rocked on its pivot. Said lever 13 is forked at its other end, the two fork members 15 15 embracing the stopper-tube 1 and resting normally upon the flange 3, as shown, the top of said iiange being eut away to form a seat in which the forks 15 15 lie, so as to give a smooth surface. The ends of the said lever members 15 l5 lie beneath the ends of the limbs of said yoke 8, so that as the said lever 13 is rocked on its pivot by pressing down on the thumb-piece 14 the forks 15 15, acting on the ends of the limbs of the yoke 8, will force the sleeve 4, yoke 8, and cap l1 to the position shown in Fig. 4 and unstopper the bottle.

It will be apparent that if the powder or granulated substance within the bottle be forced forward into the neck of the bottle by inverting the same or by smartly throwing it to volley the contents into the neck a portion of the powder will be received in the pocket formed by the concaved cap 11 and the concave flange 12 of the stopper-tube. Under these conditions if the bottle be held in a horizontal position (see Fig. 4) and the stopper-cap moved to its open position vby means of lever 13 acting upon the yoke 8 and sleeve 4 the charge of powder in the pocketbetween the cap 11 and ange 12 will fall and be delivered upon a tooth-brush or wherever desired, such delivery being facilitated by reason of the concaved faces of the cap 11 and flange 12, which offer but little frictional resistance to the tendency of the powder to fall. To insure the delivery of the charge, however, and to overcome the tendency of flnely-pulverized powders to cohere and mass, the ends of the forks 15 15 of the lever 13 are roughened, preferably by providing them with a series of serrated or ratchet-like projections 16, (see Fig. 3,) which ride under the ends of the downwardly-projecting limbs of the yoke 8 as the lever 13 is moved and vibrate or shake the said yoke 8 and its pivotally-pendent cap 1l, so that any possibility of the charge of powder sticking between the cap 11 and the flange 12 is obviated.

From the foregoing it will be seen that a simple, efficient, and convenient deliveringstopper for bottles is provided, one which is easy of manipulation, reliable in action, delivering a fixed amount of powder, and one which reduces Waste to a minimum.

While I have shown and described a particular construction of my invention, and that the best now known to me,I wish it to be understood that this is but a mere illustrative embodiment of the same, capable of considerable variation within the skill of the mechanician, without departing from my invention, and I do not, therefore, limit myself, except so far as I am limited by the terms of the appended claims, to anything shown and described.
